BLUEAIR Air Purifiers for Large Rooms, Cleans 3,048 Sqft In One Hour

The Blue Pure 211i+ Max HEPASilent™ smart air purifier is a powerful and efficient device that quickly cleans large spaces. Independently evaluated for safety standards and third-party tested for performance, this air purifier has a Clean Air Delivery Rate (CADR) of 410 for fine smoke particles, dust, and pollen.

The air purifier's proprietary RealTrack algorithm uses fan speed, usage time, and pollution levels to accurately calculate the filter's condition and notify you when it needs to be replaced, typically within 9 months. To ensure optimal performance, it is recommended to use the genuine Blueair Blue Pure F2MAX replacement filter (B08KPHRLXR).

Designed with the latest Scandinavian design trend in mind, the Blue Pure Max air purifiers come with a customizable, washable fabric pre-filter in Stockholm Fog, while Limestone, Moss, and Sand pre-filters are sold separately. This unique feature sets Blueair apart from other air purifier brands.

Compared to the Blue 411 Auto model, the new Blue Pure 411a Max and 411i Max have a higher pollen CADR on the high fan speed. Additionally, Blueair models with both mechanical and electrostatic filtration achieve less noise and use less energy than similar models with only H13 HEPA mechanical filtration.

The Blue Pure 211i+ Max HEPASilent™ air purifier is certified by Quiet Mark and delivers exceptional performance with up to 83% faster cleaning and 50% less noise than other models. It can clean a space of up to 3,048 square feet in 60 minutes, 1,524 square feet in 30 minutes, or 635 square feet in about 12.5 minutes on the high setting.

The HEPASilent dual filtration technology used in this air purifier effectively removes at least 99.97% of tiny airborne particles, including viruses and smoke, down to 0.1 microns. It also captures pet dander, pollen, mold allergens, and dust, while the carbon filter traps light household odors from smoking, pets, and cooking.

The Blueair smart air purifier app allows for customizable features, including scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack accurate filter tracking technology. Additionally, Alexa voice control is available for hands-free operation.
